Side chain liquid crystal polymers combine properties characteristic of polymers with those low molar mass mesogens. Due to these two properties SCLCPs have potential applications in various fields, ranging from optical data storage, non-linear optics, to being the stationary phase in gas chromatography and high performance liquid chromatography. SCLCPs are generally prepared by covalently linking rigid mesogens through flexible spacers. In recent years, self-assembly through specific interactions, such as hydrogen bonding, ionic, ionic-dipolar and charge transfer interactions has been recognized as a new strategy for constructing SCLCPs. These supramolecular materials have some advantages over the covalently bonded systems as a dynamic function, environmental compatibility, and low energy processing.
